Add .openworm.yml metadata to geppetto repositories

[mwatts15]

Automated repository crawler for the documentation would be lacking several geppetto libraries. This issue is to add a basic .openworm.yml to libraries in the geppetto project that indicates the relationships between them.

@mwatts15 Is there a doc/file somewhere outlining all the mandatory/optional fields in the .openworm.yml?

@pgleeson I talked with @cheelee and understand there isn't (atm). But I've looked through all the files and found these keys so far:

openworm_docs/build.py

Lines 190 to 208 in 4022f3c

See https://github.com/openworm/org.geppetto/blob/master/.openworm.yml and https://github.com/openworm/openworm_docs/blob/master/.openworm.yml for ideas...
